The upcoming EU Hydrogen Bank pilot auction and trilogue discussions are focussing minds on the future of hydrogen. Jonas Lotze and Massimo Moser at TransnetBW and Janina Erb, Roman Flatau, Felix Greven and Max Labmayr at d-fine present the results of their modelling of two hydrogen sourcing scenarios: "Global Market" (GM) where the import of hydrogen into Europe is unrestricted, and "Energy Resilient Europe" (ERE) where almost all hydrogen is … [Read more...]
Annual Energy Efficiency improvements must double to meet climate targets. We know how to do it
Global energy intensity – a measure of how efficiently the global economy uses energy – improved by just over 2% in 2022. That needs to double to 4% annually to 2030 to meet global efficiency targets, explains Brian Motherway at the IEA. If achieved, by 2030 one unit of energy used will generate 40% more economic output than today. That’s huge, and shows why few other policy areas offer such widespread benefits. More than half of the 150 … [Read more...]
The world needs 200,000 Offshore Wind turbines by 2050: mapping the locations, constraints
Hugo Putuhena, Fraser Sturt and Susan Gourvenec at the University of Southampton summarise the results of their methodology that determines where to locate the hundreds of thousands more offshore wind turbines the world needs to meet net-zero targets. The world may need as many as 200,000 offshore turbines by 2050, generating 2,000GW. At the end of 2022, 63GW had been installed worldwide, so that means 32 times current capacity. If the “power … [Read more...]
Russia’s oil export revenue rebounded in March–April. Why aren’t the EU, U.S. and partners enforcing the price cap?
The Price Cap Coalition (PCC) - composed of Australia, Canada, the EU, Japan, the UK, and the U.S. – are failing to either enforce or lower the cap on Russian oil exports as promised, says a report summarised here from the Centre for Research in Energy and Clean Air (CREA). Had it done so, Russian revenues could have been slashed by €22bn (37%) since December by lowering the price cap for crude oil to $30/barrel and revising the caps for oil … [Read more...]
IEA’s new CCUS projects database: a tool for driving much needed progress
The IEA has made available for the first time its CCUS projects database. The number of countries with plans to develop CCUS now stands at 45, with seven more countries - in central and southern Europe, the Middle East, and Southeast Asia – joining the list in 2022. The database covers CO2 capture, transport, storage, and utilisation projects worldwide commissioned since the 1970s, and have an announced capacity of more than 100,000 tonnes/year … [Read more...]
Analysis: U.S. IRA subsidies put two-thirds of Europe’s battery production pipeline at risk
Major battery manufacturing projects earmarked for Europe are now looking to site themselves in the U.S. to take advantage of its IRA subsidies, according to a new report by T&E. It says over two-thirds of lithium-ion battery production planned for Europe – a pipeline potential of 1.8 TWh - is now at risk of being delayed, scaled down or cancelled. The nations most at risk of losing the business are Germany, Hungary, Spain, Italy, the UK and … [Read more...]
Heating Households and Buildings: Heat Pumps will be up to three times cheaper than Green Hydrogen
A new study concludes that heating from 100% green-hydrogen would be up to three times more expensive than one based on 100% electrification of buildings with heat pumps. Josh Gabbatiss at Carbon Brief summarises the findings, who says it’s yet more evidence to push back against the voices of politicians and fossil-fuel companies wanting to see hydrogen in the household and buildings heating mix (for example, the UK is planning a “hydrogen … [Read more...]
Embodied Carbon Emissions: understanding the different methodologies being used around the world
The measurement of the embodied carbon emissions of goods tells us what greenhouse gas emissions are generated during the production and transportation of those goods. This achieves two main things. Firstly, it allows producers to understand where their emissions are coming from, and so reduce them. Secondly, it opens the door to putting a price on those emissions, thus incentivising producers to reduce them. But, as Max Gruenig at E3G explains, … [Read more...]
What’s stopping even bigger Wind Turbines? Blade speed and flexing? More likely manufacturing and installation capacity
Bigger wind turbines make cheaper energy. The sector’s unexpectedly rapid successes in designing and building bigger and bigger turbines has been one of the major success stories of the clean energy sector. In 2023, the biggest turbines in the world will start generating electricity off the coast of the UK. Each of General Electric’s Haliade X turbines stands 260m high from sea level and can generate 13MW at under £50/MWh (€56/$61). But how big … [Read more...]
COP 27: a way forward for methane, fossil fuel (not just coal) phase-out, and U.S.-China competition?
COP 27 was never expected to have the impact that COP 26 did, and that’s how it turned out, explain Ben Cahill, Sandeep Pai and Taiya Smith at CSIS. But there are three issues that can have long term positive impacts if carried forward successfully. The first is some good news on methane emissions. The U.S., the EU, Japan and other countries announced an important producer-consumer effort to cut greenhouse gas emissions from traded gas, while … [Read more...]
China’s electricity market design should choose from successes in Europe, UK, Australia, USA
China has made substantial initial progress in its electricity market reform, but it still faces an uphill struggle in promoting the consumption of renewables, resource allocation across provinces and regions, and unlocking demand side potential. To help choose the best solutions China could do well to look at the “Handbook on Electricity Markets”, says Daisy Chi at ECECP. The 600-page book looks at the current state of power markets around the … [Read more...]
How European nations are using tax to promote zero-emissions cars
Taxation is an effective way to steer people towards zero-emission cars. But there is wide variation between European countries in how this is done, and therefore the results. Griffin Carpenter at Transport & Environment (T&E) summarises their report “The good tax guide: A comparison of car taxation in Europe” that covers seven forms of car taxation across 31 European countries in detail. The ultimate goal should be to create a clear … [Read more...]
Energy Security: what if the UK government had not “cut the green crap” from 2013
The UK provides an example of a government that cut back its green ambitions only to see its energy security suffer. In 2013, then-prime minister David Cameron told his ministers to “cut the green crap”. That led successive governments to downgrade home energy efficiency, requirements for new homes to be “zero carbon”, end subsidies for onshore wind and solar, and effectively ban onshore wind in England. What if the UK had stayed on its … [Read more...]
Copenhagen will miss its 2025 net-zero target: a case study of how pledges fail
Copenhagen is going to miss its 2025 net-zero target. The reason can be taken as a template for why we may soon see other failing pledges from governments and corporates. Kirstine Lund Christiansen at the University of Copenhagen and Inge-Merete Hougaard at Lund University explain that Copenhagen’s emissions overspill stems from an unrealistic dependence on technology when the promise was first made in 2012. As the target date got closer, other … [Read more...]
Energy security concerns are building momentum for Nuclear
The IEA’s latest report on nuclear power recommends a doubling of capacity by 2050. It emphasises that, though many advanced economies are planning a decline, 32 nations have nuclear today and reactors are now under construction in 19 countries. It’s evidence of a momentum behind nuclear power that should be further stimulated by recent spikes in oil, gas and electricity prices, says the IEA. Russia and China remain nuclear advocates, which … [Read more...]
